CAS 1222-05-5 · Musk · Polycyclic · Not restricted by IFRA
Musk G Pure is HHCB, the clean, sweet polycyclic musk that most people know as Galaxolide. It is the 'fresh laundry' musk in detergents and a quiet workhorse in fine fragrance, adding volume and staying power without drawing attention to itself.
What it smells like
Clean and sweet with a soft floral-woody musk, like freshly washed cotton. It is diffusive and very long-lasting, so you notice it more in the dry-down than on the first sniff.
How perfumers use it
Use it as a base note and fixative across florals, fresh and woody accords, and in attar-style oils. Blending it with a macrocyclic musk such as ethylene brassylate or Habanolide gives a rounder, more expensive-smelling musk base than any single musk alone.
Blends well with: Ethylene Brassylate, Habanolide / Globalide, Iso E Super, Hedione, Ambroxan.
